"As I do with many fans, I briefly met and took a photo with Irene Lopez at her request," Culkin told E! News on Monday. "I have had no contact with this woman in any capacity, social or otherwise before or since that picture was taken. Any reports to the contrary are false."

Someone may want to tell Lopez, who played coy about their budding romance last week. "The last time I was with him, no one found out about it. I don't know what happened this time that the newspaper heard about it," she told E!.

Culkin's rep was quick to shoot down her claims: "The reports that Macaulay Culkin is dating Irene Lopez are completely false. We are disappointed that Ms. Lopez has told E! Entertainment fictitious stories regarding Mr. Culkin."
